Den foreliggende opfindelse angår en betjeningsforsats til elektriske kommando- og meldeapparater, især nødafbrydere, og omfattende en låseindretning for driftsstillingen, idet en skyder ved hjælp af en trykknap er forskyde-5 ligt anbragt i apparathuset og idet skyderen endvidere er omgivet af et forskydningslegeme, i hvilket under fjedertryk stående, indbyrdes modstående låsestifter er holdt på plads i tværgående boringer, idet hver låsestift samvirker med to i forskydningsretningen på afstand fra hverandre på begge 10 sider af et fremspring beliggende rastesteder, og fremspringet på den til hvilestillingen svarende side har en skråflade, idet der desuden mellem trykknappen og husets frontflade er indsat en ydre trykfjeder og der mellem trykknappen og forskydningslegemet er anbragt en indre trykfjeder og tryk-15 knappen er forbundet med skyderen, idet endvidere de andre låsesteder i overensstemmelse med driftsstillingen er således udformet, at en udløsning sker blot ved drejning af trykknappen omkring dens længdeakse.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operating attachment for electrical command and alarm devices, in particular emergency switches, and comprising a locking device for the operating position, a slider being slidably disposed in the apparatus housing and the slider further enclosed by a shear body. which, under spring pressure, mutually opposed locking pins are held in transverse bores, each locking pin cooperating with two spaced apart spaced directions on both sides of a projection, and the projection on the side corresponding to the resting position has an inclined surface; in addition, an outer compression spring is inserted between the pushbutton and the front surface of the housing and an inner compression spring is provided between the pushbutton and the displacement body, and the pushbutton is connected to the slider, furthermore, the other locking points in accordance with the operating position are designed so that a release just happens by turning the pushbutton about its longitudinal axis.

En betjeningsforsats af den ovennævnte type er kendt 20 fra DE-A-3 304 589 (FR-A-2 521 768). Ved denne indretning er den indre skyder ved den nedre ende forsynet med et legeme, som fastholder stifter i en første låsestilling. Det er tilstrækkeligt med en forskydning over blot en meget lille vejlængde for at frigive stifterne og forårsage en udløsning.An operating attachment of the above type is known from DE-A-3 304 589 (FR-A-2 521 768). In this device, the inner slider is provided at the lower end with a body which holds pins in a first locking position. A displacement over just a very small path length is sufficient to release the pins and cause a release.

25 Da udløsninger, således som praksis viser, ofte sker på grund af en ren fejltagelse og helt uønsket, kan der ved den kendte indretning indtræffe uønskede forstyrrelser. Ved denne indretning er der nemlig indrettet to par låsestifter for ved hjælp af forskellige låsestillinger på grundlag af en 30 indikatorring at kunne skelne mellem tilsigtede udløsningsforløb og omkoblinger, som er forårsaget af tilfældig berøring.25 As solutions, as practice shows, often occur due to a mere mistake and completely undesirable, undesirable disturbances may occur in the known device. Namely, in this device, two pairs of locking pins are arranged so as to be able to distinguish, by means of different locking positions, on the basis of an indicator ring, between the intended triggering and switching caused by accidental contact.

En anden konstruktion af en betjeningsforsats er kendt fra DE-A-32 07 725. Ved denne har skyderen en gennem-35 brydning i form af en tværboring, i hvilken der befinder sig to rastekugler, som ved hjælp af en fjeder trykkes fra hinanden ind i diametralt modsat i huset placerede fordybninger. Mellem skyderen og huset påAnother construction of an operating attachment is known from DE-A-32 07 725. By this, the slider has a breakthrough in the form of a transverse bore, in which are two resting balls which are pressed apart by means of a spring. in diametrically opposite recesses in the housing. Between the slider and the house on

2 den ene side og skyderen og trykknappen på den anden side er der indsat trykfjedre på en sådan måde, at de til stadighed forsøger at forskyde skyderen, samt trykknappen fra den første rastestilling til den anden rastestilling afhængigt af 5 driftsstillingen. Det er altså her tilstrækkeligt med et let tryk på trykknappen for at frigøre kuglerne fra den første fordybning, således at skyderen så på grund af en forspændt fjeder forskydes slagagtigt, indtil kuglerne smutter ind i fordybningerne svarende til driftsstillingen. Til tilbage-10 kobling til hvilestillingen bevæges trykknappen i aksial retning mod kraften af de to fjedre, indtil kuglerne igen griber ind i fordybningerne i en første hvilestilling. Ap-paratet er udtrykkeligt udformet således, at det under undgåelse af en drejebetjening af trykknappen skal være sikker 15 mod overlistning og nærmere betegnet ved, at afbrydeprocessen alene udløses ved indtrykning af trykknappen, hvorefter omskiftningen forløber helt uden indflydelse udefra.2 on one side and the slider and pushbutton on the other side, compression springs are inserted in such a way that they continuously try to displace the slider, and the pushbutton from the first rest position to the second rest position depending on the operating position. Thus, a slight push of the pushbutton is sufficient here to release the balls from the first recess, so that the slider then, due to a biased spring, is shifted stroke-wise until the balls enter the recesses corresponding to the operating position. To return to the rest position, the pushbutton is moved axially to the force of the two springs until the balls again engage the recesses in a first rest position. The apparatus is expressly designed so that, while avoiding a rotary operation of the pushbutton, it must be secure against over-loading and, more specifically, that the interrupting process is triggered only by pressing the pushbutton, after which the switching proceeds completely without outside influence.

Endvidere kendes der fra DE-A-31 13 034 en låseindretning for sikringsafbrydere, som skal forhindre en ube-20 vidst genindkobling af sikrings afbryderen og som skal lade erkende, om sikringsafbryderen selv har udløst eller om nødudløsningsknappen er blevet betjent. Til dette formål er der indrettet en på tværs af bevægelsesretningen af drivstødstangen en særlig konstruktion med en spærreskyder.Furthermore, DE-A-31 13 034 discloses a locking device for circuit breakers which is to prevent an unintentional reconnection of the circuit breaker and which must acknowledge whether the circuit breaker itself has triggered or if the emergency release button has been operated. For this purpose, a special structure with a locking slider is arranged transversely of the direction of movement of the drive shaft.

25 Spærre skyderen forhindrer en genindkobling af sikringsaf bryderen. Til genindkobling er det nødvendigt at bevæge en drivtast ind i udgangsstillingen.25 Locking the slider prevents reconnection of the circuit breaker. For reconnection, it is necessary to move a drive key into the home position.

Ved denne kendte indretning er det ganske vist muligt i driftsstillingen, altså i stillingen efter betjeningen, 30 forbigående at låse en trykknap, dog har denne kendte konstruktion fælles med andre på markedet forekommende betjeningsforsatse, at udløsningen fra hvilestillingen, dvs. nødafbrydelsen allerede sker ved en let indtastning eller berøring. Det har i praksis altid vist sig, at udløsningen mange 35 gange sker helt utilsigtet og ofte også ubemærket, fx ved at en person går forbi og berører udløseren med et beklædnings-In this known device, it is possible, in the operating position, that is to say, in the post-operative position, to temporarily lock a pushbutton, however, this known construction has in common with other operating prescriptions that the release from the rest position, ie. the emergency shutdown is already done by a light touch or touch. In practice, it has always been found that the triggering happens many 35 times completely unintentionally and often also unnoticed, for example by a person passing and touching the trigger with a garment.

På denne baggrund har opfindelsen til opgave at til-5 vejebringe en betjeningsforsats, der kun ved hjælp af et bevidst, kraftigt tryk på trykknappen og forskydning af trykknappen gennem en forholdsvis stor vejlængde bevirker en udløsning, som også samtidig låser driftsstillingen og udefra giver dette til kende, og ved hvilken tilbageføringen i hvi-10 lestillingen kun er mulig gennem en ikke uden videre nærliggende betjening.In view of the above, the invention has the object of providing an operating attachment which, only by means of a deliberate, strong push of the pushbutton and displacement of the pushbutton through a relatively large path length, causes a release which also simultaneously locks the operating position and from outside gives and in which the reversal in the position of the wheel is possible only through an operation which is not immediately obvious.

Den stillede opgave løses ifølge opfindelsen ved at forskydnings legemet er udformet som en cylindrisk bøsning, som er forskydeligt anbragt på den ligeledes cylindrisk ud-15 formede del af skyderen, at skyderen på omkredsen har indbyrdes modstående, affasede føringsflader og bøsningens in-derflade med tilsvarende affasninger er tilpasset skyderdelen, at skyderen udviser en i forskydningsretningen udvidet gennembrydning, at boringerne til optagelse af låsestifterne 20 i bøsningen er udformet gennemgående og som hulstifter med halvkugleformet afrundede yderender udformede låsestifter er dimensioneret så lange, at de delvis rager ind i den udvidede gennembrydning i skyderen og er bevægeligt ført i denne, at der er indrettet kun to hulstifter i hvilke en 25 eneste trykfjeder griber ind med sine ender, at de andre rastesteder har en i tværsnit seglformet del, således at hulstifterne ved trykknappens drejning trykkes kontinuerligt tilbage ud af rastestederne og ind i bøsningens boringer og skyderens gennembrydning, og at der til den på afstand fra 30 trykknappen beliggende ende af bøsningen slutter sig et i forskydningsretningen forskydeligt betjenings legeme, som ved hjælp af anslag har begrænset slaglængde.The present task is solved according to the invention in that the shear body is formed as a cylindrical bush which is slidably mounted on the likewise cylindrical part of the slider, that the slider has circumferentially opposed, beveled guide surfaces and the inner surface of the sleeve with corresponding bevels are adapted to the slider part, that the slider exhibits a breakthrough extended in the shear direction, that the bores for receiving the locking pins 20 in the sleeve are formed throughout and are shaped as hollow pins with hemispherical rounded ends locking pins so that they protrude partially into the opening. the slider and is movably guided therein that only two hollow pins are arranged in which a 25 single compression spring engages with its ends, so that the other resting places have a cross-sectional seal-shaped part, so that the hollow pins are continuously pushed out of the resting places at the rotation of the push button. and into the bush bores and the breakthrough of the slider, and that at the end of the bush located at a distance from the pushbutton, an actuator slidable in the shear direction joins, which by means of impact has a limited stroke.

På denne måde opnås det, at der ved simpel tastning eller berøring, respektive en let indtrykning af trykknappen 35In this way, it is achieved that with a simple keystroke or touch, a slight press of the pushbutton 35 is respectively performed.

Kun ved et kraftigt tryk på trykknappen og overvindelse af en tydelig modstand sker der en udløsning, og denne sker slagagtigt. Låsningen i drifts-5 stillingen sker med simple tekniske midler, men er imidler tid meget sikker og kan kun ophæves igen ved en drejning af trykknappen.4, no release occurs and the pushbutton can simply return to its resting position. Only by a strong push of the pushbutton and overcoming a clear resistance does a triggering occur and this occurs in a stroke. The locking in the operating position takes place with simple technical means, but is, however, very safe and can only be revoked by turning the pushbutton.

Flangen på den cylindriske ansats 8 overdækkes af en krave på gevindansatsen 5. Mod denne krave har bunden 7 af hu-5 set 9 anlæg. Den på tegningen underste del af huset 9 overdækkes af en cylindrisk kappe 73, der nedefter går over i en set ovenfra kvadratisk eller rund del 74.

The flange of the cylindrical shoulder 8 is covered by a collar on the threaded attachment 5. Against this collar, the bottom 7 of the housing 5 is set 9. plant. The lower part of the housing 9 in the drawing is covered by a cylindrical sheath 73, which then descends into a square or circular top view from above. The flange of the cylindrical abutment 8 and the collar 6 is adapted correspondingly square or round. Ca. in the middle of the height of the housing there is 10 on the circumference a circumferential groove 10, into which a ring bead 11 is clamped on the lower edge of a sealing cap 12.

En anden, øverste kant 13 af tætningshætten 12 er fastgjort i en ringnot 14 på en indvendig cylindrisk ansats 15 på en trykknap 16, således at den bøjelige, eksempelvis af gummi 15 bestående tætningshætte aflukker samtlige i det følgende be skrevne bevægelige dele af betjeningsforsatsen støvsikkert udefra.A second upper edge 13 of the sealing cap 12 is secured in a ring groove 14 on an inner cylindrical shoulder 15 on a push button 16, so that the flexible, for example rubber 15 sealing cap seals off all the movable parts of the operating kit described hereinafter .

På indersiden af trykknappen 16 er der mellem ansatsen 15 og en let konisk udefter forlænget kant 17 af tryk-20 knappen et hulrum 23 til optagelse af en del af tætningshætten 12, især i driftsstillingen af betjeningsforsatsen, således som det fremgår af fig. 2. På den ydre endeflade af trykknappen 16 er der et skilt 20, fortrinsvis en rød plade, til en nødafbryder, som er forsynet med fremspring 25 21 og 22, osm griber ind i udsparinger 18 og 19. Skiltet 20 er således også udskifteligt.On the inside of the pushbutton 16, there is a cavity 23 for accommodating a portion of the sealing cap 12, especially in the operating position of the operating attachment, as shown in FIG. 2. On the outer end surface of the pushbutton 16, there is a sign 20, preferably a red plate, for an emergency switch provided with projections 25 21 and 22, etc., which engages in recesses 18 and 19. The sign 20 is thus also interchangeable.

Trykknappen 16 har en central boring 24, gennem hvilken en skrue 25 er ført igennem og ned i en gevindboring 28 i hovedet 27 på en skyder 26, således at trykknappen 16 30 er fast forbundet med skyderen 26 og samtidig er den øvre kant 13 af tætningshætten indspændt tæt, nærmere betegnet mellem den cylindriske ansats 15 på trykknappen og den øvre skudler 29 af skyderens 26 hoved 27.The push button 16 has a central bore 24 through which a screw 25 is passed through and down into a threaded bore 28 in the head 27 of a slider 26, so that the push button 16 30 is firmly connected to the slider 26 and at the same time the upper edge 13 of the sealing cap tightly tightened, more specifically between the cylindrical shoulder 15 of the pushbutton and the upper jaw 29 of the head 27 of the slider 26.

Skyderen 26 er omgivet af en udvendig cylindrisk 35 bøsning 36, nærmere betegnet i det væsentlige på den nederste halve del af skyderen som det fremgår af fig. 1 og 2.

6 huset 9 er der indsat en ydre trykfjeder 31- En anden, indre trykfjeder befinder sig melelm skulderen 29 på hovedet 27 på skyderen 26 på den ene side og den på tegningen øverste endeflade af bøsningen 36 på den anden, idet der til bedre 5 fastholdelse af den nederste ende af den indre trykfjeder 32 i denne endeflade af bøsningen 36 er forarbejdet en ringformet udsparing 35. Til bedre føring af den nederste ende af den ydre trykfjeder tjener føringskanten 34 på huset 9, som rager noget frem fra den øvre endeflade 33. De mod ho-10 vedet 27 af skyderen 26 hvilende ender af trykfjedrene 31 og 32 er adskilt fra hinanden ved hjælp af en ringforsats 30, der ligeledes bidrager til en forbedring af fastholdelsen af trykfjederen.In the housing 9, an outer compression spring 31 is inserted. Another internal compression spring is located between the shoulder 29 of the head 27 of the slider 26 on one side and the upper end surface of the sleeve 36 on the other, for better retention. of the lower end of the inner compression spring 32 in this end face of the sleeve 36 is formed an annular recess 35. For better guidance of the lower end of the outer compression spring, the guide edge 34 of the housing 9 protrudes slightly from the upper end surface 33. The ends resting against head 27 of the slider 26 of the compression springs 31 and 32 are separated from each other by means of a ring attachment 30 which also contributes to an improvement in the retention of the compression spring.

Bøsningen 36 har to over for hinanden liggende tvær-15 boringer 37 og 38, gennem hver af hvilke en hulstift 39 og 40 kan gribe igennem. Disse hulstifter tjener som det beskrives nærmere nedenfor som låseelementer. Hulstifterne 39 og 40 er halricugleformet afrundet ved deres yderste ender.The sleeve 36 has two opposite transverse bores 37 and 38 through each of which a hollow pin 39 and 40 can pass through. These hollow pins serve as described further below as locking elements. The hollow pins 39 and 40 are hemispherical rounded at their outer ends.

De presses til stadighed ved hjælp af en trykfjeder 41 ud-20 efter eller fra hinanden, idet trykfjederen med enderne som vist griber ind i hulstifterne. Hulstifterne 39 og 40 er så lange, at de med enderne delvis griber ind i en gennem-brydning 42 på siderne 26 som vist. De bør imidlertid kun være så lange, at de i indefter trykket tilstand mod kraf-25 ten af trykfjederen 41 ikke rammer hinanden med deres indvendige endeflader. Gennembrydningen 42 på skyderen 26 er i forskydningsretningen gjort bredere, dvs. i den ifølge fig.They are pressed continuously by means of a compression spring 41 outwards or apart, the compression spring having the ends as shown engaging the hollow pins. The hollow pins 39 and 40 are so long that, with the ends, they partially engage in a breakthrough 42 on the sides 26 as shown. However, they should only be so long that, when pressed down against the force of the compression spring 41, they do not hit each other with their inner end faces. The breakthrough 42 on the slider 26 is made wider in the shear direction, ie. in the FIG.

De indre flader 45 og 46 på bøsningen 36 er tilsvarende udformet plane, således at disse flader glider mod hinanden og fremfor alt frembringer en dreje-sikring mellem skyderen 26 og bøsningen 36, således at derThe substantially cylindrical slider 26 has, on a portion of its circumference, opposite beveled guide faces 43 and 44 extending perpendicular to the image plane 35 of FIG. 1 and 2. The inner faces 45 and 46 of the sleeve 36 are similarly formed planar so that these faces slide against each other and, above all, provide a pivot lock between the slider 26 and the sleeve 36, so that

7 kun kan finde en glidebevægelse i forskydningsretningen sted mellem skyderen og bøsningen, men ikke en samtidig forskydning i en drejeretning i forhold til længdeaksen.7, only a sliding movement in the shear direction can take place between the slider and the bushing, but not a simultaneous shear in a direction of rotation relative to the longitudinal axis.

Ved den nederste ende af skyderen 26 er der fastskruet 5 et trugformet holdeelement med en føringscylinder 48 ved hjælp af en central skrue 49. Herved fastholdes et betjeningslegeme 58, som ved dets øverste endeflade har en ydre fremstående føringskant 59 for den nederste ende af bøsningen 36. Endvidere har betjeningslegemet 58 udefter, dvs. på fig. 1 og 10 2 nedefter førte lister 60 og 61, hvis ender har ydre fortyk kelser 62 og 63. Slaglængden for betjeningslegemet 58 begrænses herved og ved anslag 64 og 65 på den indvendige væg af gevindansatsen 5.At the lower end of the slider 26, a trough-shaped retaining member is secured with a guide cylinder 48 by means of a central screw 49. This maintains an operating body 58 which has at its upper end surface an outer projecting guide edge 59 for the lower end of the sleeve 36. Further, the operating body has 58 outwards, i. in FIG. 1 and 10 2 downwardly guide strips 60 and 61, the ends of which have outer thicknesses 62 and 63. The stroke length of the operating body 58 is hereby limited and by stops 64 and 65 on the inner wall of the threaded shoulder 5.

I den iøvrigt cylindriske indvendige væg af huset 9 er 15 der parallelt med billedplanet på fig. 1 og 2 forløbende riller og 51, samt 52 og 53, hvis' bredde vinkelret på billedfladen er således dimensioneret, at de derindi ragende dele af hulstifterne 39 og 40 kan bevæge sig deri med spillerum. De øvre riller 50, 51 danner de første rastesteder, og de nedre 20 riller 52 og 53 det andet sæt rastesteder. Mellem rillerne 50,51 i det første sæt rastesteder og rillerne 52,53 i det andet sæt rastesteder er der anbragt fremspring 54 og 55, der således flugter med den cylindriske indvendige væg af huset 9. Ved rillerne 50 og 51 er fremspringene 54 og 55 forsynet 25 med indefter hældende skråfalder 56 og 57. Det andet sæt rastesteder, altså rillerne 52 og 53, forløber ved de den øverste ende begrænsende flader af fremspringene 54 og 55 vinkelret på forskydningsretningen af skyderen 26 og bøsningen 36. Det andet sæt rastesteder 52 og 53 er svarende til drifts-30 stillingen ifølge fig. 2 udformet således, at en udløsning kun kan ske ved drejning af trykknappen 16 omkring dens længdeakse. Et udførelseskesempel på dette er illusteret på fig. 3-9. Herved har det andet sæt rastesteder 52,53 i tværsnit de på fig. 5 og 7 viste sejlformede, i omkredsretningen 35 udvidede udtagninger 67 og 68, således at hulstifterne 39 og 40 ved drejning af trykknappen kan trykkes tilbage ind i bøsningen 36 og skyderen 26 ud af det andet sæt rastesteder til den tilstødende del af den cylindriske indervæg af huset.In the otherwise cylindrical inner wall of the housing 9, 15 is parallel to the image plane of FIG. 1 and 2 extending grooves and 51, as well as 52 and 53, the width of which is perpendicular to the image surface is dimensioned such that the portions of the hollow pins 39 and 40 therein can move therein with clearance. The upper grooves 50, 51 form the first resting places, and the lower 20 grooves 52 and 53 the second set of resting places. Between the grooves 50, 51 in the first set of resting places, and the grooves 52,53 in the second set of resting places, projections 54 and 55 are arranged which thus align with the cylindrical inner wall of the housing 9. At the grooves 50 and 51 the projections 54 and 55 provided with inclined inclined slopes 56 and 57. The second set of resting points, i.e. grooves 52 and 53, extend at the upper end limiting surfaces of the projections 54 and 55 perpendicular to the shear direction of the slider 26 and the bushing 36. The second set of resting points 52 and 53 is similar to the operating position of FIG. 2 is designed so that a release can be effected only by turning the pushbutton 16 about its longitudinal axis. An exemplary embodiment of this is illustrated in FIG. 3-9. Hereby, the second set of resting places 52.53 in cross-section has those of FIG. 5 and 7, recesses 67 and 68 extended in the circumferential direction, so that, by turning the pushbutton 39, the hollow pins 39 and 40 can be pushed back into the sleeve 36 and the slider 26 out of the second set of resting places to the adjacent part of the cylindrical inner wall of the the House.

De seglformet udvidede udtagninger 67 og 68 er fortrinsvis placeret ved den side af rillerne 52 og 53 så en drejning af trykknappen 16 i driftsstillingen ifølge fig. 2 kan ske i urvisernes retning, når låsningen skal ophæves.The seal-shaped expanded recesses 67 and 68 are preferably located at the side of the grooves 52 and 53 so that the push button 16 is rotated in the operating position according to FIG. 2 can occur in the clockwise direction when the locking is to be lifted.

5 Som det fremgår især af fig. 4, 6, 8 og 9 er den indvendige væg af huset 19 forsynet med en yderligere i forskydningsretningen forløbende rille 69, der i forhold til rillerne 50,51 og 52,53 er forsat ca. 90°. I området, som omtrent svarer til det andet sæt rastesteder med rillerne 52 og 53, samt 10 udvidelserne 67 og 68, er rillen ensidigt trapezformet forsynet med en udvidelse 70, idet overgangen fra udvidelsen 70 til rillen 69 dannes ved hjælp af en skråflade 71. På højde med hulstifterne 39 og 40 og ligeledes forskudt 90° omkring omkredsen er der udvendigt på bøsningen 36 fastgjort 15 en tap 72, som griber ind i rillen 69, respektive udvidelsen 70.5 As can be seen in particular from FIG. 4, 6, 8 and 9, the inner wall of the housing 19 is provided with a further groove 69 extending in the shear direction, which, relative to the grooves 50,51 and 52,53, is provided approx. 90 °. In the region approximately similar to the second set of resting sites with grooves 52 and 53, as well as extensions 67 and 68, the groove is unilaterally trapezoidal provided with an extension 70, the transition from the extension 70 to the groove 69 being formed by an inclined surface 71. At the level of the hollow pins 39 and 40 and also displaced 90 ° about the circumference, on the outside of the sleeve 36 a pin 72 is secured which engages the groove 69 and the extension 70 respectively.

Virkemåden af den ovenfor beskrevne betjeningsforsats er i det væsentlige som følger. Når betjeningsforsatsen ifølge fig. 1 befinder sig i hvilestilling, ligger fortykkelserne 20 62,63 på listerne 60,61 an mod anslagsfremspringene 64 og 65, således at den øverste stilling af de bevægelige dele er begrænset på trods af en vis forspænding af trykfjedrene 31 og 32. Hulstifterne 39 og 40 sidder i første rastestilling ved den underste ende af rillerne 50 og 51. Når man nu tryk-25 ker trykknappen ud af stillingen i fig. 1 lidt nedefter, vil trykfjedrene 31 og 32 blive mere eller mindre stærkt sammentrykket og skyderen 26 forskyder sig tilsvarende nedefter. Som følge af de udvidede gennembrydninger 42 vil hulstifterne 39 og 40 ikke tvangsmæssigt bringes med af trykfje-30 deren 41, således at hulstifterne 39 og 40 og bøsningen 36 i begyndelsen forbliver i begyndelsesstillingen. Hvis trykknappen 16 efter berøring eller en mindre forskydning.igen frigives, vender den tilbage til udgangsstillingen uden at en udløsning eller omskiftning har fundet sted. Først når 35 trykknappen indtrykkes så stærkt og bevidst, at ikke blot den ydre trykfjeder 31, men fremfor alt også den indvendige trykfjeder presses så stærkt -sammen, at hulstifterne 39 ogThe operation of the operation described above is essentially as follows. When the operating attachment of FIG. 1 is in a resting position, the thickens 20 62,63 on the strips 60,61 abut the abutment projections 64 and 65, so that the upper position of the moving parts is limited despite some bias of the compression springs 31 and 32. The hollow pins 39 and 40 is in the first rest position at the lower end of grooves 50 and 51. Now, when the push button is pressed out of the position of FIG. 1 slightly downwardly, the compression springs 31 and 32 will be more or less strongly compressed and the slider 26 displaces correspondingly downward. As a result of the extended breakthroughs 42, the hollow pins 39 and 40 will not be forcibly carried by the compression spring 41, so that the hollow pins 39 and 40 and the bush 36 initially remain in the initial position. If the pushbutton 16, after touching or a slight displacement, is released, it returns to its initial position without triggering or switching. Only when the pushbutton is pressed so strongly and deliberately that not only the outer compression spring 31, but above all also the internal compression spring is pressed so strongly together that the hollow pins 39 and

9 40 ved de skrå flader 56,57 trykkes så langt indefter, at de afrundede hoveder på hulstifterne befinder sig fuldstændigt inden i bøsningen 36, forskyder den indre trykfjeder 32 som følge af den stærke spænding bøsningen 36 5 slagagtigt nedefter, hvormed også betjeningslegemet 68 med listerne 60 og 61 slagagtigt bevæger sig nedefter. De sidstnævnte står i forbindelse med det egentlige, ikke viste afbrydeapparat, således at der derved sker en slagagtig omkobling eller udløsning af den elektriske afbryder. Slaglæng-10 den af bøsningen 36 og af betjeningslegemet 68 er begrænset ved hjælp af anslagsfremspringene 64 og 65, dvs. afsatspladerne 66 på betjeningslegemet 68 ligger da ved stillingen ifølge fig. 2 an mod disse anslagsfremspring 64,65. Efter overvindelse af fremspringene 54 og 55 mellem de to raste-15 stillinger kan hulstifterne 39,40 under virkningen af tryk fjederen 41 igen spredes ud fra hinanden, således at de befinder sig i den anden rastestilling ved den øverste ende af rillerne 52,53 ifølge fig. 2. En tilbageføring af de bevægede dele og trykknappen 16, der i denne stilling viser, at 20 en afbrydelse har fundet sted, kan hverken ske ved et for nyet tryk eller ved tilbagetrækning af trykknappen, da hulstifterne ligger an mod de beskrevne nedre vinkelret på forskydningsretningen forløbende flader af fremspringene 64 og 65. Når nu trykknappen 16 bevidst drejes som vist på fig. 7, vil 25 hulstifterne mod kraften af trykfjederen 41 blive trykket ind efter langs fladerne på de seglformede udvidelser 67,68 indtil de ligger an mod den tilstødende cylindriske væg eller den indvendige flade af huset 9. I denne dreje- eller svingbevægelse deltager såvel trykknappen 16 som skyderen 26 30 og bøsningen 36, samt det trugformede holdeelement 47, men ikke betjeningslegemet 58 med listerne 60 og 61. Med dreje-eller svingbevægelsen er de på bøsningen 36 fastgjorte tappe 72 blevet drejet med fra stillingen ifølge fig. 6 til stillingen ifølge fig. 8. På grund af bredden af udvidelsen 70 35 og ved anslag af tappen 72 mod de to vertikale flader af udvidelsen 70 er omfanget af drejebevægelsen af trykknappen 16 begrænset. Når man nu ved stillingen af hulstifterne 39, 109 40 at the inclined surfaces 56,57 is pressed so far inward that the rounded heads of the hollow pins are completely within the bush 36, the internal compression spring 32 is displaced downwardly due to the strong tension of the bush 36, with which also the operating body 68 with the strips 60 and 61 move downwardly. The latter are connected to the actual switching device (not shown), so that there is a stroke-like switching or tripping of the electrical switch. The stroke length of the sleeve 36 and of the operating body 68 is limited by the impact projections 64 and 65, i.e. the landing plates 66 on the operating body 68 are then at the position of FIG. 2 against these projections 64.65. After overcoming the protrusions 54 and 55 between the two rake positions, the hollow pins 39,40 can, under the action of the pressure, the spring 41 again be spread apart so that they are in the second rake position at the upper end of the grooves 52.53 according to FIG. 2. A return of the moving parts and the pushbutton 16, showing in this position that an interruption has occurred, cannot be effected either by a new pressure or by the pushing of the pushbutton as the hollow pins abut the described lower perpendicular to the faces of the projections 64 and 65. Now that the pushbutton 16 is deliberately turned as shown in FIG. 7, the hollow pins against the force of the compression spring 41 will be pressed inwards along the faces of the seal-shaped expansions 67,68 until they abut against the adjacent cylindrical wall or the inner surface of the housing 9. In this turning or swivel movement, the push button 16 also participates. such as the slider 26 30 and the sleeve 36, as well as the trough-shaped holding member 47, but not the operating body 58 with the strips 60 and 61. With the rotary or pivotal movement, the pins 72 fixed on the sleeve 36 have been rotated from the position of FIG. 6 to the position of FIG. 8. Due to the width of the extension 70 35 and upon impact of the pin 72 against the two vertical faces of the extension 70, the extent of the rotary movement of the pushbutton 16 is limited. By now at the position of the hollow pins 39, 10

40 og tappen 72 ifølge fig. 7 og 8 frigiver trykknappen, kan den sammen med skyderen og bøsningen igen bevæge sig opefter, hvorved kappen 72 glider langs den skrå flade 71 og bevirker en tilbagedrejning til udgangsstillingen (4).40 and the pin 72 of FIG. 7 and 8 release the pushbutton, it, together with the slider and bushing, can again move upwards, whereby the sheath 72 slides along the inclined surface 71 and causes a return to the initial position (4).

5 Under denne tilbagebevægelse glider de afrundede hoveder på hulstifterne 39,40 som vist på'fig. 9 i retning af pilen mod den cylindriske indvendige væg af huset 9 indtil de igen kan smutte ind i det første sæt rastestillinger ved den underste ende af slidserne 50 og 51.5 During this backward movement, the rounded heads of the hollow pins 39,40 slide as shown in Figs. 9 in the direction of the arrow towards the cylindrical inner wall of the housing 9 until they can again enter the first set of rest positions at the lower end of slots 50 and 51.

10 Den ovenfor omtalte ringforsats 30 har ikke blot til opgave at adskille enderne af trykfjedrene 31 og 32 fra hinanden eller at gribe ind mellem disse, men tillige har denne ringforsats den i det følgende forklarede væsentlige betydning. Hvis det skulle forekomme, at den ene eller den 15 anden trykfjeder fastklemmes, taber fjederkraft eller endog knækker, bliver betjeningsforsatsen ifølge opfindelsen ikke virkningsløs, men ringforsatsen 30 bevirker, at den med sin frie ende ved indtrykning af trykknappen rammer den på tegningen øverste endeflade af bøsningen 36, og tvangsmæssigt 20 driver denne nedefter, således at udkoblingen eksempelvis ved en nødafbryder i alle tilfælde kommer til at finde sted.10 The ring attachment 30 mentioned above is not only intended to separate the ends of the compression springs 31 and 32 from or to intervene between them, but also this ring attachment has the essential significance explained in the following. If one or the other compression spring should be clamped, lose spring force or even break, the actuating device according to the invention does not become ineffective, but the ring attachment 30 causes it to hit the upper end surface of the drawing with its free end by pressing the push button. the bushing 36, and forcibly 20, drive it downwardly so that, for example, in the event of an emergency switch, the switch-off occurs.
